DOOR CHECK AND STOP.

Specification of Letters Patent.

Patented May 15, 1906.

Application filed July 81, 1905. Serial No. 271,878.

, To all whom it may concern.-

chard, in the county of Hampdenand State of Massachusetts, have invented certain new and useful Improvements in DoorOhecks and Stops, of which'the following is a full, clear, and exact description.

This invention relates to improvements in door-checks of a kind which are entirely mechanical in character and which may serve both as a yielding resistance or check against the movements of the door and as a stop for positively confining the door, when desired, in any fully or partially opened position.

The objects of the invention are to provide an appliance for the purpose indicated which is very simple and inex ensive of construction, having little liabi 'ty to derangement after protracted use and having entire efficiency both as a check and a stop, with susceptibility for variation of the yielding pressure against which the door swings.

The invention consists'in a device having arts in combination and of construction as ereinafter fully and clearly described in conjunction with the accompanying drawings, and as set forth in the claims.

In the drawings, Fi ure 1 is a erspeotivc view showing the checl i as applie in relation to a doorjamb or casing and a door. Fig. 2

is a perspective view Showing in separated relations the more important portions of the device; and Fig. 3 is a sectional view as taken on line 3 3, showing in properly-assembled relations for action the same parts as are included in Fig. 2. 4

Similar characters of reference indicate I corres onding parts in all of the views.

In t e drawings, A and B represent members for attachment, respectively, to a door- 1' amb and to a door, or vice versa. The member A comprises a back or attachment plate 10, having the forwardly-extending lug 12,.made

with a vertical socket 13, in which the down-v wardly-turned member 14 of the horizontal rod C has a pivotal or swiveling engagement, whereby the rod may freely swing in a horizontal plane. The member B, here shown as attached on the side of the door, comprises the back or attachment plate 16 and the forwardly-extending lug 17, having the horizontal perforation 18 therethrough, through and said lug having the upstanding screwstud 19.

D represents a saddle or yoke-shaped shoe having through its middle or arch portion the vertical aperture 22, by which provision the shoe is engaged about the screw-stud 19, while its op osite horizontally extending bearing mem ers or shoes 23, longitudinally grooved at their under sides, as seen at 24, not only frictionally bear on the upper side of the rod, but so engage the vlatter as to be prewhich said rod 0 has a guiding engagement,

vented from any revoluble displacing movement.

having its lower end resting on the top of the saddle-shoe, while the top of this spring is borne against by the thumb-nut g, which screw engages on the upper extremity of the stud 19.

As particularly shown in Figs. 2 and. 3, the nut is constructed with the downwardlyopening recess 30, such cup-sha ed lower port1on of the nut enveloping an giving space for occu ancy therewithin of the spring.

Mani estly by loosening the nut tension on the spring and the friction between the shoe members 24 24 and the rod may be very slight, so that the door may be swimg without any material resistance to its movements. By turning the thumb-nut downward in a moderate extent the frictional en agement between the saddle-shoes and rod wi 1 become such as to constitute an adequate check, with possibility for positively movin the door to any position desired and with t e assurance that the doonwill remain where placed, and, again, by turning the nut sufiiciently far downward the limits for compression of the s ring may be exceeded and the saddles oe may be forced with such a hard bind against the rod as to prevent any movement 0 the rod relatively to the shoe, even were the door to be quite forcibly pushed, so that under the latter-described condition the device becomes a stop.

The arrangement and connection of the parts of this appliance in relation to the jamb and door are preferably as illustrated in the drawings, although manifestly a reversal of the arrangement could be made in an entirely operative manner--that is, the member or fitting A might be attached on the door I and the parts. B, d, and g might be located at mem , the member relatively to which the rod is or near t e jamb.

Having thus described my invention, what I claim, and desire to secure by Letters Patent is- 1 In a door-check, members for attachment respectively to a door-jamb and to a door, a rod, swiveled to one of said members to swing in a horizontal plane, and having a guiding enga ement horizontally through the other %er, and a friction device associated with guided, comprising a saddle-shaped shoe having opposite rod-bearing members, a spring for pressing the shoe against the rod and a nut-screw engaging an extension of the rodengaging member and coacting saidspring.

2. n an appliance of the character described, in combination, members for attachment to a door and a door-ja'mb, a rod pivotally connected to one of said mem-bers,and the other of said members having a perforation for the engagement of the rod horizontally therethrough, and provided with an an ularly-extending screw-stud, a saddle or yo eshaped shoe, intermediately vertically apertured, engaging about said screw-stud having the opposite members thereof grooved at their under side, and in frictional bearing against the rodat opposite sides of said perforated member, a spiral spring encircling the screwstud and reacting downwardly against the saddle-shoe, and a nut engaging the screwstud, and'fortension'ingthe spring, and con structed with a cup-shaped downwardlyopen lower portion for enveloping the spring Signed by me at Springfield, Massachusetts, in presence of two subscribing Witn-esses,
